Abstract

In this paper we investigate the effects of spatial curvature as well as the thermal effects on a Jaynes–Cummings model. For this purpose we suppose that the field is initially in thermal circle coherent state, that contains both spatial curvature and thermal properties of the surrounding space. Then, to study the curvature and thermal effects on the dynamical properties of the model, we consider photon distribution, Mandel parameter of the field, and population inversion of the atom. The field in this system exhibits nonclassical features which depend on the curvature, and also the temperature of the physical space. Our analysis demonstrates that spatial curvature can serve as a protective mechanism against loss of quantum behavior in our system.
